Based on the SDS-3 E-beam lithography machine, the electrostatic deflection of the folded plate structure was used instead of the electrostatic deflection of the plate.
A new form concrete shell aqueduct in folded plate structure is introduced. It keeps the basic advantages of the U-shell aqueduct and avoids its main disadvantages.
Applying the principle of minimum total potential energy, the spline subdomain method of folded plate structures is derived.
